From the High Line to the skyline

The Spiral, by architects BIG, visually extends the landscape of the nearby High Line Park up and around the skyscraper's exterior, creating green outdoor terraces on all 66 storeys

From the architects:

Developed by Tishman Speyer and built by Turner, The Spiral is home to major companies including Pfizer, Debevoise & Plimpton, Turner Construction and HSBC, among others. 

Located on West 34th Street between Hudson Boulevard and 10th Avenue, The Spiral neighbours the elevated High Line and Bella Abzug Park on Manhattan’s west side. 

The commercial high-rise, designed by BIG in collaboration with Adamson Associates and structural engineer WSP Cantor Seinuk, measures 66 storeys and 360,00 m², reaching a height of 314.4m. 

The Spiral is pursuing LEED Silver certification and the tower is BIG’s first completed supertall, and first completed commercial high-rise in New York.

From street level, the tower draws the eye upwards to the ribbon of greenery that extends the High Line beyond West 34th Street and into the Manhattan skyline. 

Reminiscent of a conservatory, the tower’s glass panel façade offers passersby a look into the building’s bright and spacious lobby, adorned with artwork by Dutch studio DRIFT and lush foliage.

The lobby can be accessed via entrances on both Hudson Boulevard and 10th Avenue.

As a gesture to the building’s surroundings, The Spiral’s lobby incorporates seven different metals to honour the area’s industrial history, with floor panels measured to the exact dimensions of the precast concrete planks spanning the High Line.

The Spiral slowly reduces in volume as it rises, following the zoning envelope of the site. 

Its stepping language resonates with the design aesthetics of classic Manhattan skyscrapers such as the Empire State Building and Rockefeller Center, while its slender proportions and use of modern materials and detailing speak to the design features of contemporary high-rise architecture.

The Spiral punctuates the northern end of the High Line, and the linear park appears to carry through into the tower, forming an ascending ribbon of lively green spaces, extending the High Line to the skyline, says Bjarke Ingels, founder and creative director, BIG. 

"The Spiral combines the classic Ziggurat silhouette of the premodern skyscraper with the slender proportions and efficient layouts of the modern high-rise," he says. 

"Designed for the people who occupy it, The Spiral ensures that every floor of the tower opens up to the outdoors, creating hanging gardens and cascading atria that connect the open floor plates from the ground floor to the summit into a single uninterrupted workspace. 

"The string of terraces wrapping around the building expands the daily life of the tenants to the outside air and light, the architect says. 

"As the trees and grasses, flowers and vines have taken root over the past two summers, The Spiral is slowly becoming an ascending ribbon of green wrapping around the entire silhouette of the tower – like a 300m-tall vine at the scale of the city’s skyline.”

Cascading landscaped terraces and hanging gardens climb the tower in a spiralling motion to create a unique, continuous green ribbon that wraps around the façade of the building and supplies each office floor with readily accessible terrace space.

With approximately 1208m² of outdoor space, a landscape of The Spiral’s size has never been installed at or above 91m elevation in New York City. 

Most of the plant species on the ground cover are native to the American prairie, making them resistant to high winds and droughts.

As the building rises, a second layer of shrubs and taller bushes that blossom in winter are introduced, and finally, the landscape is crowned with single- and multi-stem trees that flower as early as February, along with vertical trellises with English and Boston ivy that keep their leaves through the winter. 

The plant palette differs on each side of the building depending on sun orientation and endurance against high-velocity winds.

The Spiral pioneers a new landscape typology by bringing gardens to a high rise, says Giulia Frittoli, partner, BIG. 

"Its continuous cascade of greenery from one level to another provides office spaces with a new vertical dimension of social and biophillic connectivity. 

"Designed to strengthen collaboration and wellbeing, each terrace hosts plantings specific to the varying daylight, winds and temperatures at every floor of the tower," he says. 

"These gardens will welcome neighbouring birds, bees and butterflies to expand New York's biodiversity to the city skyline.” 

As The Spiral ascends, each floor’s accessible terrace offers impressive views over Manhattan, the Hudson River and New Jersey. Select floors offer a double height amenity space and the option to connect adjacent floors via a grand staircase, suggesting an alternative to elevators and encouraging interaction amongst colleagues.

The Spiral promotes a contemporary workplace where nature becomes an integrated part of the office environment and spatial features are continuously adaptable to the changing needs of its occupants. 

To foster a connection to the outdoors and support The Spiral’s interior foliage, a generous ceiling height and specially selected exterior glass coating enables a deeper incursion of natural light. 

The building’s water management system collects overflow rainwater to treat and redistribute throughout the tiered landscaping, allowing it to save millions of gallons of water annually. 

This not only promotes sustainable irrigation – it also further cements The Spiral as a green addition to the Manhattan skyline.

The Spiral was named the world’s Best Tall Building in its category by The Council on Tall Buildings and Urban Habitat,
